Zap2it has been looking back at the best performances from each stage of the
"American Idol" finals and now we're taking a gander at the Top 4. This week on "Idol," the contestants get songs by Leiber and Stoller. But who are you favorites from the Top 5 phase of year's past? Vote below.

In looking back at the Top 4 performances, we are struck first by how much the Idol machine used some form of disco as a Top 4, which definitely worked out best for Season 3. And we also remembered how in love we have been with several of the Idol duets. We wish they would've started doing that earlier - a Carrie/Bo duet or a Daughtry/McPhee duet would've been awesome.

Also - there were a lot of good Top 4 performances. Guess that's why they made the Top 4, huh? So who wins your vote for the best Top 4 performance?
